Drive solutions for welding guns

Servo-pneumatic or electric – you decide which is best for you

As you well know, welding guns need to be precise and reliable. It is not just the reproducibility of the spot welds that plays a key role in the quality and efficiency of the welding process; flexibility and speed are just as important – even under the most challenging conditions. This has led to requirements that Festo has optimally incorporated in its drive solutions for welding guns. The intelligent solutions control welding guns extremely precisely. You decide which is best for you – the X gun or the C gun, servo-pneumatic or electric.


Intelligent components for high process reliability

The intelligent system components of our drive solutions communicate bidirectionally. The data provided enables you to monitor all the processes and to model them in Industry 4.0. Bus communication between the components ensures that the controller can exchange data with the higher-order controller. During commissioning, the welding gun controller detects all connected components, which means that hardly any parameter data need to be entered manually. Commissioning couldn’t be simpler.

Servo-pneumatics versus electrics

Servo-pneumatics is all about a controlled pneumatic positioning technology that guarantees dynamic response, power and flexibility. Our specialists have now transferred these advantages into an electric variant to meet the requirements for greater energy efficiency in new production sites with a low-pressure network. Savings in energy costs and carbon emissions are therefore the top priority. Make the most of both technologies, even – depending on the application requirements – by mixing them within a welding cell.

Servo-pneumatic drive solution


Advantages of the servo-pneumatic drive solution

  • Cost-efficient solution
  • High speed and dynamic response
  • Robust technology
  • Lightweight
  • Everything from a single source
  • Also suitable for low-pressure networks
  • When used in a mix of technologies: preferably with C guns
Electric drive solution



Advantages of the electric drive solution

  • Energy-efficient solution (especially with high forces)
  • Compact design in low-pressure network (compared to servo-pneumatics)
  • Compatible with various electric drives
  • Innovative drive concept including pneumatic compensation
  • When used in a mix of technologies: preferably with X guns
